Device and method for detecting color uniformity of three-color polyester

Abstract

The invention discloses a three-color polyester color uniformity detection device, and relates to the field of computer color photometers. The three-color polyester color uniformity detection device comprises a tester main body, the back surface of the tester main body is fixedly connected with a fixed seat, the upper surface of the tester main body is provided with an imported white board, and an extruder is arranged right above the imported white board. According to the color uniformity detection device for the three-color polyester, when the pressure borne by the surface of the three-color polyester needs to be changed for multiple groups of experimental tests, the pressure between the squeezer and the imported white board is changed through the pressure adjusting assembly, so that different detection and debugging effects are achieved, the detection result is more accurate, and the detection efficiency is improved. When the number of folded layers or the thickness of the sample is changed, the distance between the squeezer and the imported white board is adjusted through the rotating assembly, so that normal detection can be carried out.

Description

technical field [0001] The invention relates to the technical field of computer color measuring instruments, in particular to a three-color polyester color uniformity detection device and method thereof. Background technique [0002] The working principle of the computer colorimeter is to divide the light reflected by the object into intervals of 5 or 10nm under a specific light source, and the reflectance data at different wavelengths, that is, the spectral reflectance curve. The price is often related to the accuracy of the instrument. The higher the accuracy, the more expensive the price. Computer color measuring instruments are mainly divided into two types: desktop and portable. Computer color measurement requires the sample to be tested to be close to the ideal sample. However, there are few samples that fully meet such characteristics in actual production, such as The number of folded layers of the sample, the direction, the background and the pressure on the surface ...

[0002] The working principle of the computer colorimeter is to divide the light reflected by the object into intervals of 5 or 10nm under a specific light source, and the reflectance data at different wavelengths, that is, the spectral reflectance curve. The price is often related to the accuracy of the instrument. The higher the accuracy, the more expensive the price. Computer color measuring instruments are mainly divided into two types: desktop and portable. Computer color measurement requires the sample to be tested to be close to the ideal sample. However, there are few samples that fully meet such characteristics in actual production, such as The number of folded layers of the sample, the direction, the background and the pressure on the surface of the sample will all affect the accuracy of the measurement

[0003] The products that the existing computer color measuring instrument can detect are all fixed. When the number of folded layers of the sample or the thickness of the sample itself changes, the distance between the tester and the product cannot be changed, resulting in pressure on the sample during the test. Change, or cannot be placed into the sample, resulting in the inability to test, and the pressure on the surface of the sample cannot be changed, so that the detection cannot be debugged, and the accuracy of the measurement is affected, so we propose a three-color polyester color Uniformity detection device and method thereof
